New York’s new bridge opening to traffic

The second span of the New York’s new cable-stayed bridge has now been completed and has opened to traffic. The final span of the Governor Mario M Cuomo Bridge, which replaced the Tappan Zee Bridge, has now been opened to drivers. The opening was delayed slightly due to concerns over the state of a section of the old bridge, now being demolished. The new link was constructed by a joint venture headed by 6343 Fluor. With the new bridge opening, all four lanes of eastbound traffic shifted to the new second span. The eastbound span consists of four general purpose traffic lanes, two emergency shoulders, space for a dedicated bus lane and an advanced traffic monitoring system.

The westbound bridge will remain in a temporary configuration while crews complete the bridge’s shared-use path connecting Westchester (New York) and Rockland (New York) counties for pedestrians and cyclists.

The New York State Thruway Authority, in partnership with the Fluor-led joint venture of Tappan Zee Constructors, LLC – comprised of 1021 American Bridge Company, Granite Construction Northeast, Inc. and Taylor Bros., Inc. – replaced the old bridge with a new 5km state-of-the-art, twin-span, cable-stayed bridge crossing the Hudson River between Westchester and Rockland counties. The cable-stayed main span is supported by eight 128m towers, which stand at 5° angles and feature a sleek, chamfered design. The iconic towers support 192 stay cables, which are made up of roughly 7,840km of steel strands.

The Governor Mario M Cuomo Bridge is one of the largest single design-build contracts for a transportation project in the United States and is the largest bridge project in New York state history.

New NY Bridge - Tappan Zee - main span towers poured

One of the largest US infrastructure projects is nearer completion after recent topping out of the eight main span towers of the New NY Bridge. The final concrete pour was in mid-December and all piles - more than 1,000 - have been installed in Hudson River. To date, 3,000 roadway panels for the approaches - making 5.5km in length - have been installed, according to the New York State Thruway Authority, owner of the New NY Bridge project.

I Lift NY crane places first girder on New York’s Tappan Zee Bridge

One of the world’s largest cranes has placed the first steel girder assembly for the approach span of the new NY Bridge, often called the Tappen Zee Bridge in New York. The barge-mounted I Lift NY super crane with its nearly 100m boom slowly picked up the 125m unit from its delivery barge and gently lowered it onto concrete pedestals in the Hudson River, near the Rockland County side of the bridge. The super crane will install even larger sections of the new bridge, some of which weigh around 907tonne

New York governor aims to freeze Thruway tolls, including Tappaen Zee Bridge

The governor of the US state New York, Andrew Cuomo, said he wants to spend US$22 billion over the next five year on maintaining aging roads and bridges. Cuomo also wants to give the agency responsible for maintaining the state’s major cross-state tolled freeway, the 920km Thruway, $1 billion so the agency – New York State Thruway Authority - can freeze tolls at their current rate until 2020. US media reported that his plan would also eliminate tolls for agricultural traffic. He would also offer a t

Tappan Zee takedown into the Hudson River

A controlled explosion demolished the eastern span of the old cantilever Tappan Zee Bridge across the Hudson River near New York City. The bridge, nearly 5km long, was opened in 1955 to carry traffic between the southern New England area and other regions west of the Hudson. Around 140,000 vehicles used the bridge daily. But the old bridge had deteriorated substantially and would have been too expensive to maintain or keep open for lighter traffic use. It became redundant after the new bridge of the
